The Class B Common Stock Option shall be assignable, in whole or in part and from time to

time, by ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ to any ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity. The exercise price for the shares of Class B Common Stock purchased pursuant to the Class B Common Stock Option shall be the Market Price of the Class A Common Stock as of the date of first delivery of notice of exercise of the Class B Common Stock Option by ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ (or its permitted assignee hereunder) to MSCI.

(b) MSCI hereby grants to ▇▇▇▇▇▇ ▇▇▇▇▇▇▇, on the terms and conditions set forth herein, a continuing right (the “Nonvoting Stock Option” and, together with the Class B Common Stock Option, the “Options”) to purchase from MSCI, at the times set forth herein, such number of shares of Nonvoting Stock as is necessary to allow ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities to own eighty percent (80%) of each class of outstanding Nonvoting Stock. The Nonvoting Stock Option shall be assignable, in whole or in part and from time to time, by ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ to any ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity. The exercise price for the shares of Nonvoting Stock purchased pursuant to the Nonvoting Stock Option shall be the price at which such Nonvoting Stock is then being sold to third parties or, if no Nonvoting Stock is being sold, the fair market value thereof as determined in good faith by the board of directors of MSCI.

Section 2.02. Notice. At least 20 business days prior to (i) any issuance of any shares of MSCI Stock and (ii) each date on which an event could occur that, in the absence of an exercise of the Class B Common Stock Option, would result in a reduction in the Vote Ownership Percentage or Value Ownership Percentage, MSCI will notify ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ in writing (a “Class B Common Stock Issuance Notice”) of any plans it has to issue such shares or the date on which such event could first occur. At least 20 business days prior to (x) any issuance of shares of Nonvoting Stock and (y) each date on which an event could occur that, in the absence of an exercise of the Nonvoting Stock Option, would result in any reduction in the percentage of any class of Nonvoting Stock owned by ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities or otherwise result in ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities owning less than eighty percent (80%) of each class of outstanding Nonvoting Stock, MSCI will notify ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ in writing (a “Nonvoting Stock Issuance Notice” and, together with a Class B Common Stock Issuance Notice, an “Issuance Notice”) of any plans it has to issue such shares or the date on which such event could first occur.

Section 2.03. Option Exercise And Payment. The Class B Common Stock Option may be exercised by ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ (or any ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity to which all or any part of the Class B Common Stock Option has been assigned) only for such number of shares as are necessary to prevent a ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Ownership Reduction. The Nonvoting Stock Option may be exercised by ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ (or any ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity to which all or any part of the Nonvoting

Stock Option has been assigned) only for such number of shares as are necessary for ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entities to own, in the aggregate, eighty percent (80%) of each class of outstanding Nonvoting Stock. Each Option may be exercised (to the extent then exercisable in accordance with its terms) at any time after receipt of an applicable Issuance Notice and prior to the applicable Issuance Event Date by the delivery to MSCI of a written notice to such effect specifying (i) the number of shares of Class B Common Stock or Nonvoting Stock (as the case may be) to be purchased by ▇▇▇▇▇▇ ▇▇▇▇▇▇▇, or any ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity, and (ii) a calculation of the exercise price for such shares. Upon any such exercise of either Option, MSCI will, immediately prior to the issuance or event in connection with an Issuance Event, deliver to ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ (or any ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity designated by ▇▇▇▇▇▇ ▇▇▇▇▇▇▇), against payment therefor, certificates (issued in the name of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ or its permitted assignee hereunder, or as directed by ▇▇▇▇▇▇ ▇▇▇▇▇▇▇) representing the shares of Class B Common Stock or Nonvoting Stock (as the case may be) being purchased upon such exercise. Payment for such shares shall be made by wire transfer or intrabank transfer to such account as shall be specified by MSCI, for the full purchase price for such shares.

Section 2.04. Initial Public Offering. Notwithstanding the foregoing, ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ shall not be entitled to exercise the Class B Common Stock Option in connection with the Initial Public Offering of the Class A Common Stock.

Section 2.05. Termination Of Options. The Options shall terminate upon the occurrence of a ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Ownership Reduction, other than a ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Ownership Reduction resulting from any Issuance Event in violation of this Agreement. Each Option, or any portion thereof assigned to any ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity other than ▇▇▇▇▇▇ ▇▇▇▇▇▇▇, also shall terminate in the event that the Person to whom such Option, or such portion thereof has been transferred, ceases to be a ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity for any reason whatsoever.

ARTICLE 3

REGISTRATION RIGHTS

Section 3.01. Demand Registration - Registrable Securities. (a) Upon written notice provided at any time after the Initial Public Offering Date from any Holder of Registrable Securities requesting that MSCI effect the registration under the Securities Act of any or all of the Registrable Securities held by such Holder (a “Demand Holder”), which notice shall specify the intended method or methods of disposition of such Registrable Securities, MSCI shall use its reasonable best efforts to effect the registration under the Securities Act and applicable state securities laws of such Registrable Securities for disposition in accordance with the intended method or methods of disposition stated in such request (including in a Rule 415 Offering, if MSCI is then eligible to register such Registrable Securities on Form S-3 (or a successor form) for such offering) (a “Demand Registration”); provided, that:

(i) the Holders of Registrable Securities may collectively exercise their rights to a Demand Registration on not more than five occasions;

(ii) the Holders of Registrable Securities shall not exercise their rights to a Demand Registration within the six-month period following any registration and sale of Registrable Securities effected pursuant to a prior exercise of rights to a Demand Registration;

(iii) the rights to effect a Demand Registration shall terminate on the tenth anniversary of the date of this Agreement; and

(iv) if the board of directors of MSCI determines in good faith that a Demand Registration (A) would materially impede, delay, interfere with or otherwise materially adversely affect any pending financing, registration of securities by MSCI in a primary offering for its own account, acquisition, corporate reorganization or other significant transaction involving MSCI or (B) would require disclosure of non-public material information that MSCI has a bona fide business purpose for preserving as confidential, MSCI shall be entitled to defer the filing or effectiveness of a registration statement, or to suspend the use of an effective registration statement, for the shortest period of time reasonably required (each such period, a “Blackout Period”); provided, that, MSCI shall not be entitled to invoke Blackout Periods for more than an aggregate of sixty (60) days in any 12-month period. MSCI shall notify each Holder of the expiration or earlier termination of a Blackout Period and, as soon as reasonably practicable after such expiration or termination, shall amend or supplement any effective registration statement to the extent necessary to permit the Holders to resume the use thereof in connection with the offer and sale of their Registrable Securities in accordance with applicable law.

(b) Notwithstanding any other provision of this Agreement to the contrary, a Demand Registration shall not be deemed to have been effected if no Registrable Securities are sold under the registration statement (and, therefore, not requested for purposes of paragraph (a) above).

(c) In the event that a Demand Registration shall involve, in whole or in part, an underwritten offering, the Demand Holder shall have the right to designate an underwriter or underwriters as the lead or managing underwriters of such underwritten offering reasonably acceptable to MSCI (and MSCI hereby acknowledges that ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. Incorporated is reasonably acceptable) and, in connection with each Demand Registration, the Demand Holder may select one counsel to represent all Holders participating in such offering.

(d) MSCI shall have the right to cause the registration of additional equity securities for sale for the account of any Person (including, without limitation, MSCI and any existing or former directors, officers or employees of the MSCI Entities) in any Demand Registration; provided, that, if the Demand Holder is advised in writing (with a copy to MSCI) that the inclusion of such additional equity securities in such registration would be likely to exceed the Maximum Offering Size, the registration of such additional equity securities or part thereof shall not be permitted.

(e) The Demand Holder may require that any such additional equity securities described in Section 3.01(d) be included on the same conditions as the Registrable Securities of the Demand Holder to be included therein.

(f) If the Demand Holder believes that the aggregate number of Registrable Securities requested to be included in a Demand Registration would be likely to exceed the Maximum Offering Size, the Demand Holder may request a determination of the Maximum Offering Size. In the event that the Maximum Offering Size is determined to be less than the aggregate number of Registrable Securities requested to be included in such offering, the number of Registrable Securities to be included in the registration statement shall be reduced to the Maximum Offering Size and the number of Registrable Securities in excess of the amount requested by the Demand Holder, if any, shall be allocated pro rata among the other Holders requesting to be included in such offering on the basis of the relative number of Registrable Securities then held by each such Holder; provided, that, any number in excess of a Holder’s request may be reallocated among the remaining requesting Holders in a like manner.

Section 3.02. Piggyback Registration. In the event that MSCI at any time after the Initial Public Offering Date proposes to register any of its Common Stock, any other of its equity securities or securities convertible into or exchangeable for its equity securities (collectively, including Common Stock, “Other Securities”) under the Securities Act, whether or not for sale for its own account, in a manner that would permit registration of Registrable Securities for sale for cash to the public under the Securities Act, it shall at each such time give, at least 30 days prior to the anticipated filing date of the registration statement relating to such registration, written notice to each Holder of Registrable Securities of its intention to do so and of the rights of such Holder under this Section 3.02. Subject to the terms and conditions hereof, such notice shall offer each such Holder the opportunity to include in such registration statement such number of Registrable Securities as such Holder may request (a “Piggyback Registration”). Upon the written request of any such Holder made within 15 days after the receipt of MSCI’s notice (which request shall specify the number of Registrable Securities intended to be disposed of and the intended method of disposition thereof), MSCI shall use its reasonable best efforts to effect, in connection with the registration of the Other Securities, the registration under the Securities Act of all Registrable Securities which MSCI has been so requested to register, to the extent required to permit the Piggyback Registration; provided, that:

(a) if, at any time after giving such written notice of its intention to register any Other Securities and prior to the effective date of the registration statement filed in connection with such registration, MSCI shall determine for any reason not to register the Other Securities, MSCI may, at its election, give written notice of such determination to such Holders and thereupon MSCI shall be relieved of its obligation to register such Registrable Securities in connection with the registration of such Other Securities; provided, that, such determination by MSCI shall not prejudice the rights of the Holders of Registrable Securities to immediately request a Demand Registration in accordance with Section 3.01;

(b) if the registration referred to in the first sentence of this Section 3.02 is to be an underwritten registration on behalf of MSCI (an “MSCI Piggyback”) and MSCI is advised in writing that the inclusion of all or a part of such Registrable Securities in such registration would be likely to exceed the Maximum Offering Size, MSCI shall include in such registration: (i) first, all Other Securities MSCI proposes to sell for its own account and (ii) second, the number of securities (including Registrable Securities) that such underwriters advise can be so sold without adversely affecting such offering, allocated pro rata among the holders, other than MSCI, of Other Securities (the “Other Holders”) and the Holders of Registrable Securities on the basis of the number of securities requested in accordance with this Section 3.02 to be included therein by each Other Holder and each Holder of Registrable Securities; provided, that, in the event that the Maximum Offering Size is less than all of such Registrable Securities requested to be included in such offering, any ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity may withdraw its request for a Piggyback Registration and 90 days subsequent to the effective date of the registration statement for the registration of such Other Securities request a Demand Registration in accordance with Section 3.01;

(c) if the registration referred to in the first sentence of this Section 3.02 is to be an underwritten secondary registration on behalf of Other Holders (a “Demand Piggyback”) and MSCI is advised in writing that the inclusion of such additional securities in such registration would be likely to exceed the Maximum Offering Size, MSCI shall include in such registration the number of additional securities (including Registrable Securities) that such underwriters advise can be so sold without adversely affecting such offering, allocated pro rata among the Other Holders and the Holders of Registrable Securities on the basis of the number of securities (including Registrable Securities) requested in accordance with this Section 3.02 to be included therein by each Other Holder and each Holder of Registrable Securities; provided, that, in the event that the Maximum Offering Size is less than all of such Registrable Securities requested to be included in such offering, any ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Entity may withdraw its request for a Piggyback Registration and 90 days subsequent to the effective date of the registration statement for the registration of such Other Securities request a Demand Registration in accordance with Section 3.01;

(d) MSCI shall not be required to effect a Piggyback Registration incidental to the registration of any of its securities in connection with mergers, acquisitions, exchange offers, subscription offers, dividend reinvestment plans or stock option or other executive or employee benefit or compensation plans;

(e) no registration of Registrable Securities effected under this Section 3.02 shall relieve MSCI of its obligation to effect a Demand Registration; and

(f) the right to effect a Piggyback Registration shall terminate on the tenth anniversary of this Agreement.

Section 3.03. Expenses. (a) In the case of a Demand Registration,

(i) MSCI shall pay all Registration Expenses until and including the second occasion upon which a request for a Demand Registration shall have resulted in the sale of Registrable Securities under a registration statement; and

(ii) the requesting Holders shall pay all Registration Expenses arising in connection with any request for a Demand Registration thereafter.

(b) In the case of a Demand Piggyback, each Holder of Registrable Securities exercising its rights to effect a Piggyback Registration shall be responsible for a pro rata portion of the Registration Expenses, based on the number of Registrable Securities included therein by such Holder in proportion to the total number of securities included in such registration.

Section 3.04. Registration And Qualification. If and whenever MSCI is required to effect a Demand Registration or a Piggyback Registration, MSCI shall as promptly as practicable:

(a) prepare, file and use its reasonable best efforts to cause to become effective a registration statement under the Securities Act relating to the Registrable Securities to be offered;

(b) prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective and to comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities until the earlier of (i) such time as all of such Registrable Securities have been disposed of in accordance with the intended methods of disposition set forth in such registration statement and (ii) the expiration of the 90-day period after such registration statement becomes effective; provided, that,

such 90-day period shall be extended for such number of days that equals the number of days elapsing from (x) the date the written notice contemplated by paragraph (f) below is given by MSCI to (y) the date on which MSCI delivers to the Holders of Registrable Securities the supplement or amendment contemplated by paragraph (f) below;

(c) furnish to the Holders of Registrable Securities and to any underwriter of such Registrable Securities such number of conformed copies of such registration statement and of each such amendment and supplement thereto (in each case including all exhibits), such number of copies of the prospectus included in such registration statement (including each preliminary prospectus and any summary prospectus), in conformity with the requirements of the Securities Act, such documents incorporated by reference in such registration statement or prospectus, and such other documents, as the Holders of Registrable Securities or such underwriter may reasonably request, and a copy of any and all transmittal letters or other correspondence to or received from, the SEC or any other governmental agency or self-regulatory body or other body having jurisdiction (including any domestic or foreign securities exchange) relating to such offering;

(d) use its reasonable best efforts to register or qualify all Registrable Securities covered by such registration statement under the securities or blue sky laws of such jurisdictions as the Holders of such Registrable Securities or any underwriter to such Registrable Securities shall request, and use its reasonable best efforts to obtain all appropriate registrations, permits and consents in connection therewith, and do any and all other acts and things which may be necessary or advisable to enable the Holders of Registrable Securities or any such underwriter to consummate the disposition in such jurisdictions of its Registrable Securities covered by such registration statement; provided, that, MSCI shall not for any such purpose be required to qualify generally to do business as a foreign corporation in any such jurisdiction wherein it is not so qualified or to consent to general service of process in any such jurisdiction;

(e) (i) use its reasonable best efforts to furnish to each Holder of Registrable Securities included in such registration (each, a “Selling Holder”) and to any underwriter of such Registrable Securities an opinion of counsel for MSCI addressed to each Selling Holder and dated the date of the closing under the underwriting agreement (if any) (or if such offering is not underwritten, dated the effective date of the registration statement), and (ii) use its reasonable best efforts to furnish to each Selling Holder a “cold comfort” letter addressed to each Selling Holder and signed by the independent public accountants who have audited the financial statements of MSCI included in such registration statement, in each such case covering substantially the same matters with respect to such registration statement (and the prospectus included therein) as are customarily covered in opinions of issuer’s counsel and in accountants’ letters delivered to underwriters in underwritten public offerings of securities and such other matters as the Selling Holders may reasonably request and, in the case of such accountants’ letter, with respect to events subsequent to the date of such financial statements;

(f) as promptly as practicable, notify the Selling Holders in writing (i) at any time when a prospectus relating to a registration pursuant to a Demand Registration or Piggyback Registration is required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and (ii) of any request by the SEC or any other regulatory body or other body having jurisdiction for any amendment of or supplement to any registration statement or other document relating to such offering, and in either such case, at the request of the Selling Holders prepare and furnish to the Selling Holders a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they are made, not misleading;

(g) if reasonably requested by the lead or managing underwriters, use its reasonable best efforts to list all such Registrable Securities covered by such registration on each securities exchange on which the Class A Common Stock of MSCI is then listed;

(h) to the extent reasonably requested by the lead or managing underwriters, send appropriate officers of MSCI to attend any “road shows” scheduled in connection with any such registration, with all out-of-pocket costs and expense incurred by MSCI or such officers in connection with such attendance to be paid by MSCI; and

(i) so long as the board of directors of MSCI shall not have provided by resolution or resolutions that all or some of all classes or series of the stock of MSCI shall be represented by uncertificated shares, furnish for delivery in connection with the closing of any offering of Registrable Securities pursuant to a Demand Registration or Piggyback Registration unlegended certificates representing ownership of the Registrable Securities being sold in such denominations as shall be requested by the Selling Holders or the underwriters.

Section 3.05. Conversion Of Other Securities, Etc. Subject to any limitations in Section 3.09, in the event that any Holder offers any options, rights, warrants or other securities issued by it or any other Person that are offered with, convertible into or exercisable or exchangeable for any Registrable Securities, the Registrable Securities underlying such options, rights, warrants or other securities shall continue to be eligible for Demand Registration or Piggyback Registration.

Section 3.06. Underwriting; Due Diligence. (a) If requested by the underwriters for any underwritten offering of Registrable Securities pursuant to a Demand Registration or Piggyback Registration, MSCI shall enter into an underwriting agreement with such underwriters for such offering, which agreement will contain such representations and warranties by MSCI and such other terms and provisions as are customarily contained in underwriting agreements with respect to secondary distributions, including, without limitation, indemnification and contribution provisions substantially to the effect and to the extent provided in Section 3.07, and agreements as to the provision of opinions of counsel and accountants’ letters to the effect and to the extent provided in Section 3.04(e). The Selling Holders on whose behalf the Registrable Securities are to be distributed by such underwriters shall be parties to any such underwriting agreement and the representations and warranties by, and the other agreements on the part of, MSCI to and for the benefit of such underwriters, shall also be made to and for the benefit of such Selling Holders. Such underwriting agreement shall also contain such representations and warranties by such Selling Holders and such other terms and provisions as are customarily contained in underwriting agreements with respect to secondary distributions, including, without limitation, indemnification and contribution provisions substantially to the effect and to the extent provided in Section 3.07.

(b) In connection with the preparation and filing of each registration statement registering Registrable Securities under the Securities Act pursuant to this Article 3, MSCI shall give the Holders of such Registrable Securities and the underwriters, if any, and their respective counsel and accountants, such reasonable and customary access to its books and records and such opportunities to discuss the business of MSCI with its officers and the independent public accountants who have certified the financial statements of MSCI as shall be necessary, in the opinion of such Holders and such underwriters or their respective counsel, to conduct a reasonable investigation within the meaning of the Securities Act_; provided, that, such Holders and the underwriters and their respective counsel and accountants shall use their reasonable best efforts to coordinate any such investigation of the books and records of MSCI and any such discussions with MSCI’s officers and accountants so that all such investigations occur at the same time and all such discussions occur at the same time.

Section 3.07. Indemnification And Contribution. (a) In the case of each offering of Registrable Securities made pursuant to this Article 3, MSCI agrees to indemnify and hold harmless, to the extent permitted by law, each Selling Holder, each underwriter of Registrable Securities so offered and each Person, if any, who controls any of the foregoing Persons within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and the officers, directors, affiliates, employees and agents of each of the foregoing, against any and all losses, liabilities, costs (including reasonable expenses of investigation and reasonable attorney’s fees and expenses), claims and damages, joint or several, to which they or any of them may become subject, under the Securities Act or

otherwise, including any amount paid in settlement of any litigation commenced or threatened (“Damages”), insofar as such Damages (or actions or proceedings in respect thereof, whether or not such indemnified Person is a party thereto) arise out of or are based upon any untrue statement by MSCI or alleged untrue statement by MSCI of a material fact contained in the registration statement (or in any preliminary or final prospectus included therein) or in any offering memorandum or other offering document relating to the offering and sale of such Registrable Securities prepared by MSCI or at its direction, or any amendment thereof or supplement thereto, or in any document incorporated by reference therein, or any omission by MSCI or alleged omission by MSCI to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, that, MSCI shall not be liable to any Person in any such case to the extent that any such Damages arise out of or relates to any untrue statement or alleged untrue statement, or any omission, if such statement or omission shall have been made in reliance upon and in conformity with information relating to a Selling Holder or another holder of securities included in such registration statement furnished to MSCI by or on behalf of such Selling Holder, other holder or underwriter, as the case may be, specifically for use in the registration statement (or in any preliminary or final prospectus included therein), offering memorandum or other offering document, or any amendment thereof or supplement thereto. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of any Selling Holder or any other holder and shall survive the transfer of such securities. The foregoing indemnity agreement is in addition to any liability that MSCI may otherwise have to each Selling Holder, other holder or underwriter of the Registrable Securities or any controlling person of the foregoing and the officers, directors, affiliates, employees and agents of each of the foregoing; provided, further, that, in the case of an offering with respect to which a Selling Holder has designated the lead or managing underwriters (or a Selling Holder is offering Registrable Securities directly, without an underwriter), this indemnity does not apply to any Damages arising out of or relating to any untrue statement or alleged untrue statement or omission or alleged omission in any preliminary prospectus or offering memorandum if a current copy of the prospectus (or such amended or supplemented prospectus, as the case may be) or offering memorandum was not sent or given by or on behalf of any underwriter (or such Selling Holder or other holder, as the case may be) to such Person asserting such Damages at or prior to the written confirmation of the sale of the Registrable Securities as required by the Securities Act and such current copy of the prospectus (or such amended or supplemented prospectus, as the case may be) or offering memorandum would have cured the defect giving rise to such Damages.

(b) In the case of each offering made pursuant to this Agreement, each Selling Holder, by exercising its registration rights hereunder, agrees to indemnify and hold harmless, and to cause each underwriter of Registrable Securities included in such offering (in the same manner and to the same extent as set forth in Section 3.07(a)) to agree to indemnify and hold harmless, MSCI, each other

underwriter who participates in such offering, each other Selling Holder or other holder with securities included in such offering and in the case of an underwriter, such Selling Holder or other holder, and each Person, if any, who controls any of the foregoing within the meaning of the Securities Act and the officers, directors, affiliates, employees and agents of each of the foregoing, against any and all Damages to which they or any of them may become subject, under the Securities Act or otherwise, including any amount paid in settlement of any litigation commenced or threatened, insofar as such Damages (or actions or proceedings in respect thereof, whether or not such indemnified Person is a party thereto) arise out of or are based upon any untrue statement or alleged untrue statement by such Selling Holder or underwriter, as the case may be, of a material fact contained in the registration statement (or in any preliminary or final prospectus included therein) or in any offering memorandum or other offering document relating to the offering and sale of such Registrable Securities prepared by MSCI or at its direction, or any amendment thereof or supplement thereto, or any omission by such Selling Holder or underwriter, as the case may be, or alleged omission by such Selling Holder or underwriter, as the case may be, of a material fact required to be stated therein or necessary to make the statements therein not misleading, but in each case only to the extent that such untrue statement of a material fact is contained in, or such material fact is omitted from, information relating to such Selling Holder or underwriter, as the case may be, furnished to MSCI by or on behalf of such Selling Holder or underwriter, as the case may be, specifically for use in such registration statement (or in any preliminary or final prospectus included therein), offering memorandum or other offering document. The foregoing indemnity is in addition to any liability which such Selling Holder or underwriter, as the case may be, may otherwise have to MSCI, or controlling persons and the officers, directors, affiliates, employees, and agents of each of the foregoing; provided, that, in the case of an offering made pursuant to this Agreement with respect to which MSCI has designated the lead or managing underwriters (or MSCI is offering securities directly, without an underwriter), this indemnity does not apply to any Damages arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission in any preliminary prospectus or offering memorandum if a current copy of the prospectus (or such amended or supplemented prospectus, as the case may be) or offering memorandum was not sent or given by or on behalf of any underwriter (or MSCI, as the case may be) to such Person asserting such Damages at or prior to the written confirmation of the sale of the Registrable Securities as required by the Securities Act and such current copy of the prospectus (or such amended or supplemented prospectus, as the case may be) or offering memorandum would have cured the defect giving rise to such Damages.

(c) If any proceeding (including any governmental investigation) shall be instituted involving any Person in respect of which indemnity may be sought pursuant to paragraph (a) or (b), such Person (an “Indemnified Party”) shall promptly notify the Person against whom such indemnity may be sought (the “Indemnifying Party”) in writing and the Indemnifying Party shall assume the

defense thereof, including the employment of counsel reasonably satisfactory to such Indemnified Party, and shall assume the payment of all fees and expenses; provided, that, the failure of any Indemnified Party so to notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure to notify. In any such proceeding, any Indemnified Party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party unless (i) the Indemnifying Party and the Indemnified Party shall have mutually agreed to the retention of such counsel or (ii) in the reasonable judgment of such Indemnified Party representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that, in connection with any proceeding or related proceedings in the same jurisdiction, the Indemnifying Party shall not be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) at any time for all such Indemnified Parties, and that all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Indemnified Parties, such firm shall be designated in writing by the Indemnified Parties. The Indemnifying Party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent, or if there be a final judgment for the plaintiff, the Indemnifying Party shall indemnify and hold harmless such Indemnified Parties from and against any loss or liability (to the extent stated above) by reason of such settlement or judgment. Without the prior written consent of the Indemnified Party, no Indemnifying Party shall effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Party from all liability arising out of such proceeding.

(d) If the indemnification provided for in this Section 3.07 is unavailable to the Indemnified Parties in respect of any Damages, then each such Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Damages (i) as between MSCI and the Selling Holders on the one hand and the underwriters on the other, in such proportion as is appropriate to reflect the relative benefits received by MSCI and such Selling Holders on the one hand and the underwriters on the other, from the offering of the Registrable Securities, or if such allocation is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits but also the relative fault of MSCI and such Selling Holders on the one hand and of such underwriters on the other in connection with the statements or omissions that resulted in such Damages, as well as any other relevant equitable considerations and (ii) as between MSCI on the one hand and each such Selling Holders on the other, in such proportion as is appropriate to reflect the relative fault of MSCI and of each such Selling Holder in connection with such statements or omissions, as well as

any other relevant equitable considerations. The relative benefits received by MSCI and such Selling Holders on the one hand and such underwriters on the other shall be deemed to be in the same proportion as the total proceeds from the offering (net of underwriting discounts and commissions but before deducting expenses) received by MSCI and such Selling Holders bear to the total underwriting discounts and commissions received by such underwriters, in each case as set forth in the table on the cover page of the prospectus or offering memorandum. The relative fault of MSCI and such Selling Holders on the one hand and of such underwriters on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by MSCI and such Selling Holders or by such underwriters. The relative fault of MSCI on the one hand and of each such Selling Holder on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by such party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

MSCI and the Holders agree that it would not be just and equitable if contribution pursuant to this Section 3.07 were determined by pro rata allocation (even if the underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an Indemnified Party as a result of the Damages referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 3.07, no underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Registrable Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any Damages that such underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission, and no Shareholder shall be required to contribute any amount in excess of the amount by which the total price at which the Registrable Securities of such Shareholder were offered to the public (less underwriters’ discounts and commissions) exceeds the amount of any Damages that such Shareholder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11 (f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. Each Selling Holder’s obligation to contribute pursuant to this Section 3.07 is several in the proportion that the proceeds of the offering received by such Selling Holder bears to the total proceeds of the offering received by all such Selling Holders and not joint.

(e) Indemnification and contribution similar to that specified in the preceding paragraphs of this Section 3.07 (with appropriate modifications) shall be given by MSCI, the Selling Holders and underwriters with respect to any required registration or other qualification of securities under any state law or regulation or governmental authority.

(f) The obligations of the parties under this Section 3.07 shall be in addition to any liability which any party may otherwise have to any other party.

Section 3.08. Rule 144 And Form S-3. Commencing 90 days after the Initial Public Offering Date, MSCI shall use its reasonable best efforts to ensure that the conditions to the availability of Rule 144 set forth in paragraph (c) thereof shall be satisfied. Upon the request of any Holder of Registrable Securities, MSCI will deliver to such Holder a written statement as to whether it has complied with such requirements. MSCI further agrees to use its reasonable best efforts to cause all conditions to the availability of Form S-3 (or any successor form) under the Securities Act of the filing of registration statements under this Agreement to be met as soon as practicable after the Initial Public Offering Date. Notwithstanding anything contained in this Section 3.08, MSCI may deregister under Section 12 of the Exchange Act if it then is permitted to do so pursuant to the Exchange Act and the rules and regulations thereunder.

Section 3.09. Transfer Of Registration Rights. Subject to the limitations set forth in Section 3.01(a), any Holder may transfer all or any portion of its rights under this Article 3 to any transferee of a number of Registrable Securities owned by such Holder exceeding three percent (3%) of the outstanding class or series of such securities at the time of transfer (each transferee that receives such minimum number of Registrable Securities, a “Transferee”). Any transfer of registration rights pursuant to this Section 3.09 shall be effective upon receipt by MSCI of (i) written notice from such Holder stating the name and address of any Transferee and identifying the number of Registrable Securities with respect to which the rights under this Agreement are being transferred and the nature of the rights so transferred and (ii) a written agreement from such Transferee to be bound by the terms of this Article 3 and Sections 5.03, 5.04, 5.09, 5.11 and 5.12 of this Agreement. The Holders may exercise their rights hereunder in such priority as they shall agree upon among themselves.

Section 3.10. Holdback Agreement. If any registration pursuant to this Article 3 shall be in connection with an underwritten public offering of Registrable Securities, each Selling Holder agrees not to effect any public sale or distribution, including any sale under Rule 144, of any equity security of MSCI (otherwise than through the registered public offering then being made), within 7 days prior to or 90 days (or such lesser period as the lead or managing underwriters may permit) after the effective date of the registration statement (or the commencement of the offering to the public of such Registrable Securities in the case of Rule 415 offerings). MSCI hereby also so agrees and agrees to cause each other holder of equity securities or securities convertible into or

exchangeable or exercisable for such securities (other than in the case of equity securities, under dividend reinvestment plans or employee stock plans) purchased from MSCI otherwise than in a public offering to so agree.

Section 3.11. Agency Prospectus. (a) From time to time upon request by ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ in connection with any public or registered offering of securities by MSCI or any other Person of any MSCI Stock or any Tax-Free Spin-Off of MSCI, MSCI shall prepare and file with the SEC under the Securities Act a registration statement and an “agency prospectus” or other related document to the extent necessary or desirable to permit ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ to effect agency transactions by ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. Incorporated in MSCI Stock.

(b) MSCI shall pay all Registration Expenses relating to the preparation and filing of such registration statement and agency prospectus.

(c) MSCI hereby agrees that its indemnification and contribution obligations under Section 3.07 shall apply, mutatis mutandis, to paragraphs (a) and (b) above, as if set forth in this Section 3.11.
